Se Page Object Builder

Selenium Page Object Builder

You draft a Page Object the engineer still has to wire up and run — a reusable class that encapsulates one page's locators and actions. Locators are proposals until confirmed against the real DOM.

When to use

• A page's fields/buttons/flows are described and someone wants a POM class.
• Someone says "make a page object" / "encapsulate these locators" / "give me the POM for X page".
• Inline driver.findElement calls in a test need refactoring into a page class.

Workflow

1. Identify the page's responsibilities: the elements it owns and the user actions it exposes (e.g. login(), search(), getErrorText()).
2. Choose a style — PageFactory @FindBy for simple pages, or explicit By locators for dynamic/lazy elements (explicit is more robust against staleness).
3. Assign stable locators — By.id > By.cssSelector > relative locators; avoid absolute XPath. Flag any locator you cannot confirm with a // TODO comment.
4. Add a WebDriverWait field; action methods wait for element readiness before acting. Never use Thread.sleep.
5. Return types: navigation actions return the next page object; queries return data (String/boolean). Keep methods small and intention-revealing.
6. Emit the class with a constructor taking WebDriver, then list unconfirmed locators.

Output shape

public class LoginPage {
    private final WebDriver driver;
    private final WebDriverWait wait;

    private final By username = ApprovedLoginDom.USERNAME;
    private final By password = ApprovedLoginDom.PASSWORD;
    private final By submit = ApprovedLoginDom.SUBMIT;
    private final By error = ApprovedLoginDom.ERROR;

    public LoginPage(WebDriver driver) {
        this.driver = driver;
        this.wait = new WebDriverWait(driver, ApprovedLoginDom.WAIT_TIMEOUT);
    }

    public void submitCredentials(String user, String pass) {
        wait.until(ExpectedConditions.visibilityOfElementLocated(username)).sendKeys(user);
        driver.findElement(password).sendKeys(pass);
        driver.findElement(submit).click();
    }

    public boolean isErrorShown() {
        return !driver.findElements(error).isEmpty();
    }
}

ApprovedLoginDom is required project input populated only from inspected DOM evidence. If any locator, timeout, action, or next-page behavior is unknown, leave a // TODO: confirm and list it rather than creating a concrete value.

Guardrails

• This is a draft the engineer must review and run — the class is unverified until exercised against the app.
• Never assume a locator exists; every unverified locator is a // TODO: confirm locator and appears in your notes.
• Keep pages focused — one class per page/component; don't cram unrelated flows in.
• No assertions inside the page object; assertions belong in tests.
• Never use Thread.sleep; synchronize with WebDriverWait/ExpectedConditions.
• Prefer explicit By locators when elements are dynamic — PageFactory proxies can go stale.
• Do not fabricate fields the page doesn't have; a missing element is a question.
